I don't think it's because of the lack of testing that Grosjean didn't look at his mirror and squeeze Hamilton. At the start, when you change direction, you have to look at the mirrors. He should know he was not the only one at the track.

Last year, when Senna forgot to brake early, it was the lack of testing, because Senna misdjudge the speed and his brake was cold.

After the incident packed career of Maldonado and the incident from Grosjean today I think he has a valid point

"Now that it is difficult to get as much experience of the car it makes it more risky as drivers don’t have as much experience and accidents are more likely to happen, it makes the drivers life much more hard."

Good point. I've always liked Mika - a no-nonsense driver who spots the important issues.

The more time a driver spends in the car the more he is used to it and the more comfortable he is with it

Mika admitted how much the testing helped him in F1

Seeing as most of the accidents are caused by Grosjean and Maldonado he has a point

While Hakkinen was the one who clumsily took off Senna at the Pacific GP and 10 other cars at the German GP in 94. That was with loads of testing and three seasons worth of xp.

Not so sure if he forgot that bbut okay, I admit the level of incompetence as displayed by Grosjean and Maldonado is simply gross, even taking into account that testing is very limited and they had less xp at this point than Hakkinen.
